# HIV vs E

The clearest difference is in-app purchases: HIV at none against E's 6. HIV also leads on iOS requirement (13.0 vs 15.0). E's advantage is update cadence (every 2 days vs every 7 months). On price, ads and device support there is nothing between them.

Both are free to download. E sells 6 in-app purchases, starting at $19.99 per month. HIV asks for nothing beyond the download.

HIV ships an update every 7 months, E every 2 days. The most recent releases landed on November 2, 2026 and October 31, 2026 respectively.
